Sometimes the screen and touch control get’s mixed up, so you have to change the following
in /boot/config.txt: sudo nano /boot/config.txt lcd_rotate=2
Start the epiphany browser so it automtically sets up its profile
*Switch off the screensaver and let the browser start automatically with the openHAB URL: sudo nano /etc/xdg/lxsession/LXDE-pi/autostart
add: @xset s off @xset -dpms @xset s noblank @epiphany-browser -a --profile ~/.config http://UrlToOpenhab/openhab.app?sitemap=xxx
then do a: sudo reboot
and your openhab should come up automatically
That’s it.
What I did additionally to improve the WAF (previously there was a clock where the pi now is placed)
Modified a python script I found on the web to show the current time:
If I touch the clock it disappears and comes up after 30 seconds:
Really Nice! Thanks for sharing.
I was thinking to use an old kindle for this. The E-Ink display is perfect for status information like temperature, etc.
If you’re just displaying the Openhab pages in the browser, it’s worth switching it to full-screen (“kiosk”) mode to gain a bit more display space.
Unfortunately its a little more involved than another command line option (as far as I could find).
There are instructions here, among other places
I’ve actually commented out the lines beginning ‘xset’, since I wanted the screen to blank after a while
Hi Michael,
thanks for sharing with us
I like to have a display for the living room too.
So i think about different solutions:
arduino with a e-ink display
raspberry with a touch display
android tablet
My requirements are:
-low energy
shutdown the display on the night.
The problem with the pi ist, that it has no wakeonlan. So at the evening i can shutdown, but in the morning no reboot
But it is possible the shutdown only the display.
Do you know the wattage? (Off and On)
And do you have the display on the whole day?
@schlaubi A 5V 2.5A power supply (which is what’s recommended for use with the display) can put out at most 12.5W of power, so it’s probably going to draw a little more than that at peak usage since power supplies aren’t 100% efficient. And that’s the maximum, typical usage is going to be much less.
As far as blanking the screen at night there are many ways to handle that. The backlight can be turned on/off from software so you could use a button, a PIR motion detector, link into the astro binding in openHAB etc - the possibilities are endless.
The main downside of the RPi screen that I’ve found so far is that I haven’t found a good on-screen keyboard, so you’d need to keep a keyboard handy for anything that required more than point-and-click.
